Noja Power’s OSM recloser systems are designed for a 30-year maintenance free service life, with one exception – the UPS battery in the controller. Across the globe, any utility that deploys automatic circuit reclosers (ACRs) would have a maintenance programme for the equipment. These remote devices, which are effectively computer-controlled circuit breakers installed on power poles out in the field, do require periodic maintenance. In the case of a feeder outage, a utility should expect that they can maintain contact with the de-energised reclosers for some time afterwards – providing visibility and control in emergency situations. The auto-battery test functionality is available in every RC10 and RC15 controlled Noja Power OSM recloser in the field today.
